First of all, foamed silicone rubber is a kind of environmental protection material, so it is also called additive silicone rubber. It is a kind of food grade certified product, which is composed of the ratio of silicone rubber and curing agent 1:1. The product is safe and environmentally friendly, and has five poisons and no smell. It can be fireproof at 94V to 0, temperature resistant at - 40 to 220c, and tear strength as high as 55 Kn / m, ductility up to 100%.
In order to ensure the quality of the products produced, it is necessary to operate according to the requirements of the construction, so as not to cause any quality problems. Is there any secret to the normal operation of foaming silica gel? The specific operation method is as follows:
1. The normal temperature of foamed silicone rubber is between 5 and 35 β. If we construct at low temperature, please put the products to be produced into 25 to 30 β warm water in advance and take them out after 5 minutes, so as to improve the temperature of the tank.
2. Do not directly contact with open fire and over heating.
3. The surface must be cleaned, otherwise the bonding effect of foamed silicone rubber will be affected.
4. Spray a small amount of water before operation to improve the humidity of the environment.
